(Configuration of main operation management server 100p)
The configuration of the operation management server 100p will be described with reference to the block diagram of FIG. The operation management server 100p includes an operation management manager 101p, a first operation mode storage unit 102p, and an operation mode control unit 103p. The operation management manager 101p and the first operation mode control unit 103p constitute a first operation management control unit 110p.

(1) The primary operation management manager 101p communicates with the operation management agents 141p, 151p, and 161p of each managed node to control the managed node. In an actual system, it is realized by a program (process daemon, etc.). Note that the slave operation management manager 101s communicates with the operation management agents 141s, 151s, and 161s of each management target node corresponding to the slave.
(2) The first operation mode storage unit 102p stores the “operation mode” of the primary operation management manager 101p. The “operation mode” includes “table 1” and “table 2” which will be described later with reference to FIG. Although details will be described later, “table 1” defines whether each operation management (monitoring / control) function operates independently or non-independently, and “table 2” is the operation management manager 101p. Stores in which mode the service / independent / stop operation is currently permitted. The first operation mode storage unit 102p is controlled by the operation mode control unit 103p.
(3) When the operation mode control unit 103p designates one of the service / independent / stop modes of the operation management manager 101p from the control terminal 120, the mode designated by the control terminal 120 is recorded in “table 2”. To do. In addition, the two operation management servers (operation management managers) perform control so as not to permit both to operate in the service mode. Specifically, when one operation management server is designated as the service mode from the control terminal 120, the “operation mode control unit” designated as the service mode has the “operation mode control unit” of the other operation management server. The operation mode control unit "is inquired, and if the other operation mode is already in the service mode, the service mode request designated from the control terminal 120 is rejected. The operation mode control unit 103p receives an inquiry from the operation management manager 101p when the operation management manager 101p tries to execute the operation management function, and the operation management function to be executed by the operation management manager 101p is the first operation mode. It is confirmed whether or not it matches the “operation mode” stored in the storage unit 102p, and only when it matches, the operation management manager 101p is permitted to execute the operation of the operation management function.
(4) As described above, the operation management manager 101p makes an inquiry to the operation mode control unit 103p when executing the monitoring and control functions for the managed node. When the operation mode control unit 103p receives an inquiry from the operation management manager 101p, the operation mode control unit 103p refers to the current operation mode (table 2), and the operation management function to be executed by the operation management manager 101p is the current one of “table 2”. It is determined from “table 1” whether the mode (service / independent / stopped) is met. If they do not match, the operation by the operation management manager 101p is rejected, and the operation is permitted only when they match.

(Configuration of Subordinate Operation Management Server 100s)
The configuration of the secondary operation management server 100s will be described. The configuration of the secondary operation management server 100s is the same as that of the main operation management server 100p. Note that the secondary operation management manager 101s communicates with the operation management agents 141s, 151s, and 161s of the respective management target nodes to manage the management target nodes. Further, the operation management manager 101s and the operation mode control unit 103s constitute a second operation management control unit 110s.

(Control terminal 120)
The control terminal 120 controls the operation mode for the operation management servers 100p and 100s.

(Managed node)
Each managed node has an operation management agent (first agent unit) that communicates with the operation management manager 101p of the primary operation management server 100p and an operation management that communicates with the operation management manager 101s of the subordinate operation management server 100s. An agent (second agent unit).

Next, the “operation mode” regarding the operation management function will be described.

  FIG. 4 is a diagram illustrating an “operation mode”. The “operation mode” stored in the first operation mode storage unit 102p includes “table 1” and “table 2” shown in FIG. The same applies to the “operation mode” stored in the second operation mode storage unit 102s.

  The “operation mode” in FIG. 4 will be further described. The functions of the operation management system 1000 are classified into an operation management function that can operate independently in both the primary and secondary systems, and an operation management function that operates only in one of the systems.

(Operation management function that enables independent operation of both systems)
For example, operation management functions such as event (log) monitoring, process operation monitoring, system resource monitoring (CPU / memory / disk capacity monitoring), node life / death monitoring, remote command execution, and the like can be operated independently in both systems.

(Operation management function that cannot operate both systems independently)
On the other hand, software distribution, data backup, batch job control, operation management function setting changes (changes in monitoring contents, addition / change / deletion of managed nodes, etc.) Inheritance takes place, and if they are operated simultaneously in both systems, inconsistency occurs, so independent operation is not possible.

  Therefore, the operation modes of “Table 2” in FIG. 4 are classified into the following three categories: “1. service mode”, “2. independent mode”, and “3. stop mode”.

(1. Service mode)
The service mode is a mode that provides all functions. It is mounted so that only one operation management server can operate in this mode at the same time. In the function operating in this mode, data transfer occurs at the time of mode switching.

(2. Independent mode)
The independent mode is a mode that provides only an operation management function that can operate independently. At the same time, two operation management servers (operation management managers) can operate in this mode. In the function operating in this mode, data transfer does not occur when the mode is switched.

(3. Stop mode)
The stop mode is a state in which the operation management function is stopped to perform maintenance (including reboot and system backup) or upgrade.

(1) As described above, “Table 1” in FIG. 4 is a table in which each operation management function is classified according to whether or not independent operation is possible.
(2) “Table 2” is a table that stores the current operation mode (any of service / independent / stop) instructed from the control terminal 120. Note that the operation mode control unit 103p (or the operation mode control unit 103s) operates so as not to allow both operation management managers to enter the service mode. That is, as described above, when one operation management server is instructed to the service mode from the control terminal 120, the “operation mode control unit” instructed to the service mode has the “operation mode” of the other operation management server. When the operation mode is already in the service mode, the service mode request designated from the control terminal 120 is rejected.

(Operations of operation manager and operation management agent)
FIG. 5 is a flowchart for explaining the operation of the operation management manager and the operation management agent controlled by the operation management manager. With reference to FIG. 5, operations of the operation management manager and the operation management agent will be described. In the following description of the operation, the main operation management manager 101p will be mainly described. Since the operation of the subordinate operation management manager 101s is the same, the description thereof is omitted.

(S101)
First, a system administrator (or an operation operator, the same applies below) classifies the operation management functions according to whether or not independent operation is possible as shown in “Table 1” in FIG. 4 and stores them in “Table 1” of the first operation mode storage unit 102p. Defined in In this way, the system administrator decides which operation management functions are provided in an independent operation and which operation management functions are provided in an independent operation when providing an operation management system to a managed node. Define. Specifically, when the system administrator performs a definition operation using the control terminal 120, the operation mode control unit 103p of the operation management server 100p accepts the definition, and the accepted definition is stored in the "1" of the first operation mode storage unit 102p. It is stored in “Table 1” and “Table 2”. The same applies to the operation management server 100s.

(S102)
The operation management manager 101p activates a certain operation management function among the functions described in “Table 1”.

(S103)
When starting an operation management function, the operation management manager 101p inquires of the operation mode control unit 103p whether the operation management function matches the operation mode of “Table 2” when executing the operation management function. . When the current operation mode of “table 2” is “stop mode”, the operation mode control unit 103p suppresses the operation of the operation management manager 101p and moves to the operation management agents 141p, 151p, 161p by the operation management manager 101p. Stop the operation management function.

(S104 and later)
When receiving an inquiry from the operation management manager 101p, the operation mode control unit 103p refers to the first operation mode storage unit 102p, and “table 1” indicating the operation mode of each function and “table 2” indicating the current operation mode. And confirm the operation of the query. When the current operation mode of “table 2” is “independent mode”, the operation mode control unit 103p permits the operation only when the independent / non-independence of table 1 for the activated function is “independent” (S104). Yes, S105). In this case, the operation management manager 101p executes the operation of the activated operation management function (S106). In other cases, that is, in the case of non-independence, the operation of the operation management function activated by the operation management manager 101p is not permitted (NO in S104, S107). In this case, the operation management manager 101p does not execute the operation of the activated operation management function (S108). Further, when the current operation mode of “Table 2” is “Service mode”, the operation is permitted regardless of whether “Table 1” is independent or not independent of the activated function (Yes in S104, S105). ), The operation management manager 101p executes the operation of the activated operation management function (S106).

  Next, as an example of maintenance / update of the operation management system, a case where software update of the operation management system is performed will be described.

  In the operation management system 1000, at the normal time, the primary operation management manager 101p operates in the service mode, and the secondary operation management manager 101s operates in the independent mode. That is, at the normal time, the operation mode of “table 2” in the first operation mode storage unit 102p is “service mode”, and the operation mode of “table 2” in the second operation mode storage unit 102s is “independent mode”. It has become. In this case, since the main system is in the service mode, all services of the operation management function in “Table 1” are provided, and the sub system is always in the service mode when the main system shifts from the service mode to another mode. Operate in a state where migration is possible.

  When updating the software of the operation management system 1000, as will be described later, the main operation management manager 101p is shifted to the independent mode. As a result, both the primary system and the secondary system are set to the independent mode, and the software update of the other system is performed while only the operation management function that can operate independently is provided.

  FIG. 6 is a flowchart showing an operation when the operation management software is updated. A specific operation when the operation management software is updated will be described with reference to FIG.

  First, the system administrator sets the primary operation management manager 101p to the independent mode (S201), and provides an operation management service by the secondary operation management server 100s. Specifically, it is implemented by an instruction from the control terminal 120 to the operation mode control unit 103p. That is, when receiving an instruction from the control terminal 120, the operation mode control unit 103p rewrites the current operation mode of “table 2” in the first operation mode storage unit 102p from “service mode” to “independent mode”.

  Next, the system administrator stops all the software of the primary operation management manager 101p and the operation management agents 141p, 151p, 161p (S202).

  Further, the system administrator updates the software of the primary operation management manager 101p and the operation management agents 141p, 151p, 161p (S203). The system administrator activates the operation management manager 101p and the operation management agents 141p, 151p, and 161p whose software has been updated, and confirms the connection between the operation management manager 101p and the operation management agents 141p, 151p, and 161p (S204). . When the connection is confirmed, the system administrator returns the main system to the service mode (S205). That is, the control terminal 120 rewrites the operation mode of “table 2” in the first operation mode storage unit 102p from the “independent mode” to the “service mode” via the operation mode control unit 103p. Thereby, all the services are provided by the operation management server 100p.

  As described above, when updating the operation management software, it is possible to update the software while providing only the operation management function that can operate independently on either system, so the operation management functions that cannot be provided can be minimized. it can.

  In addition, since the system can be switched between the primary system and the secondary system without taking over the data by the mode in which only the independent operation management function is operated, the system switchback at the end of the software update becomes easy.

  In the operation management system 1000 according to the first embodiment, each managed node includes a first agent unit and a second agent unit, the primary operation management server 100p includes a first operation management control unit 110p, Since the operation management server 100s includes the second operation management control unit 110s, it is possible to perform maintenance / update while continuing to provide the operation management service.

  In the operation management system 1000 according to the first embodiment, the first operation management control unit 110p and the second operation management control unit 110s execute an independent mode operation management function that does not require data transfer to each other. Maintenance and updating can be performed while the service is being provided, and the system can be easily switched back.

  Since the operation management system 1000 of the first embodiment includes the control terminal 120, it can flexibly cope with system maintenance / update.

  Since the operation management server according to the first embodiment includes the operation mode storage unit and the operation management control unit, it is possible to perform maintenance / update while continuing to provide the operation management service.

  Since the management target node according to the first embodiment includes the first agent unit and the second agent unit, it is possible to perform maintenance / update while continuing to provide the operation management service.

Embodiment 2. FIG.
The second embodiment will be described with reference to FIG. In the first embodiment, the case of updating the operation management software has been described. In the second embodiment, a case involving “system stop” such as hardware maintenance, system backup, and reboot will be described. The system configuration is the same as in the first embodiment.

  FIG. 7 is a flowchart for explaining the operation in the case of “system stop” such as reboot. With reference to FIG. 7, the operation in the case of “system stop” will be described.

  First, as in the first embodiment, the operation management functions in the first operation mode storage unit 102p and the second operation mode storage unit 102s are classified and defined as independent operation availability as shown in FIG.

  As in the first embodiment, in the normal state, the primary operation management manager 101p operates in the “service mode”, and the secondary operation management manager 101s operates in the independent mode (S301). In this case, since the primary system is in the service mode, all services of the operation management function are provided, and the secondary system operates in a state where it can be shifted to the service mode whenever the primary system shifts from the service mode to another mode.

  When performing hardware maintenance / system backup / reboot, the main operation management manager 101p is shifted to the “stop mode” (S302). As described in the first embodiment, in the “stop mode”, the operation mode control unit 103p stops the operation management function by the operation management manager 101p. In this stopped state, the system administrator performs hardware maintenance, system backup, reboot, and the like (S303).

  The system administrator activates the primary operation management manager 101p and confirms the connection between the operation management manager 101p and the operation management agents 141p, 151p, 161p (S304).

  The system administrator rewrites the operation mode of the table 2 of the first operation mode storage unit 102p, which is the main system, to “service mode” using the control terminal 120 (S305).

  With the above operation, maintenance with a stop is possible for the other system while providing only the operation management function that can operate independently in the slave system.

As described above, during server maintenance with a stop, maintenance can be performed while providing only the operation management function that can operate independently on either system, so the operation management functions that cannot be provided can be minimized. it can.
In addition, since the system can be switched between the primary system and the secondary system without taking over data by the mode in which only the independent operation management function is operated, the system switchback at the end of the maintenance becomes easy.

  In the operation management system 1000 according to the second embodiment, since the control terminal 120 can rewrite the table 2 of the operation mode storage unit of the operation management server to the stop mode, the system stop can be performed while continuing to provide the operation management service. It is possible to easily cope with the accompanying maintenance.
